Nigeria Building Cost & Bill of Quantities Generator
A real, stage-by-stage BOQ for sandcrete block construction — export just the stage you're funding right now.
Nigerian house building is almost always funded in stages — foundation this year, blockwork next, roofing when funds allow — which is exactly why a single 'total project cost' number is often the least useful thing a calculator can hand you. This generator's category structure follows Nigeria's own real stage-billing convention directly (Stage 1 Preliminaries through Stage 8 External Works & Services), and you can export just the stage you're currently funding rather than the whole project at once.
The quantities themselves are built on real, verified coefficients, not a rounded 'concrete block' guess: roughly 10 sandcrete blocks per square metre of wall and 1 bag of cement per 35 blocks at 9-inch thickness, cross-checked against a live Nigerian block calculator. Cement and iron-rod prices here move fast with exchange-rate swings, which is exactly why this tool hands you real quantities to lock in with suppliers early, not a naira figure that's already stale by the time you read it.
It also includes the real site-infrastructure items a generic BOQ tool built for a Western market leaves out entirely: a borehole for water supply and diesel generator provision for site power, both standard, budgeted line items on most Nigerian sites rather than an edge case — plus Boys' Quarters and compound fencing where your build includes them.
What's in a Nigeria BOQ from this generator
- Stage 1 — Preliminaries and site setup, including borehole and generator provision
- Stage 2 — Substructure: foundation concrete, columns and beams
- Stage 3 — Superstructure: sandcrete block walls (9-inch external, 6-inch internal), real 10 blocks/m² coefficient
- Cement bags at the real 1-bag-per-35-blocks (9-inch) ratio
- Stage 4 — Roofing structure and covering
- Doors and windows (room-count and area-based, so larger houses aren't undercounted)
- Plumbing fixtures and rough-in, electrical points
- Boys' Quarters and compound fencing (if selected)
- Export just one stage at a time — the same document your bank or supplier expects for that stage's funding release
